Application filed January 13, 1923. serial No. 612,533.

To all whom it oorwem:

- Be it known that 1, 'lnnononn lit, Mo-

'SPADDEN, a citizen of the United States, and

a suction rod guide and outlet T protectors for oil pumping apparatus, and more particularly to a device which is utilized for the above purposes during removal of the pump head for repair or substitution of parts and the reinsertion of the pump head and sucker rods, my primary object being the provision of a device which may be readily clamped in connection with an outlet T, in

order to protect the internal threads of the latter and guide the sucker rod sections, so

as to avoid in part the delays and therefore the expense of pump head repairs under the present operation.

In the accompanying drawing which illustrates'my invention and forms a part of this specification,

Figure l is a side view, partly broken away and in section, showing a casing head and adjacent parts of conventional oil pumping apparatus including the outlet l. Figure 2 is a view of substantially the sae parts, with my invention in place, and igure 3 is a'detail perspective view of my improved sucker rod guide'j and outlet T protector detached and in open position.

Referring now to these figures and particularly to Figure 1 l have shown certain portions of a conventional apparatus for pumping oil from an oil well, including the usual casing having at its upper en the usual casin head, 11, downwardly through which I: e pump tube 12 extends, the latter housing the sucker rod 13, in sectionsas usual, the sections being connected by unions and the upper end of the suction red when in ,place being connected by a similar unionshown at It with the lower end'of the polish rod 15. At the upper end of the pump tube 12, above the casing head 11 is a l 16 which threads on the pump tube and connects with a lateral or outlet pipe 17, the polish rod working through a stufin box 18 which is threaded at its lower 5911 into the up r end of -the T 16.

' As is we mean at present, whenever it is necessary to withdraw the pump head secured to the lower end of the sucker rod,

ment of leathers, the stufing box 18 is un screwed from the T1" 16 and bymeans of a superlifting apparatus, upward pull is exerted on the pohsh rod 15 until union 14:;

connecting its lower end with the upper end of the sucker rod, is substantially above the l 16. What is hown 'as an elevator is then clamped to the upper portion of the sucker rod 13 below the union 14 and rests upon the T 16 so as to support the weight of the sucker rod while the union 14 is detached;

A short section of tubing commonly lmown as a nipple is then slipped onto the lower end of the'polish rod 15, this nipple having threads on its lower end, and the polish rod is again attached to the upper end of the sucker rod 13 after which the polish rod is again connected to the lifting a paratus so that the latter supports the weight of the sucker rod and'thevelevator previously referred to is removed. lhe nipple is then shifted downwardly around the sucker rod and threadedly engaged within the upper A end-of theT 16, after which the elevator is again placed in position, this time resting on the nipple, and polish rod detached. The various sections ofthe sucker rod are errant for various purposes including the replacethen lifted and,succcssively*detached in a like manner.

According to my invention a clamp 19 is proposed, of generally cylindrical form, having two semi-cylindrical sections 20 and 21 provided upon their inner surfaces and intermediate their upper and lower ed 5 withgrooves 22 coact ng to form an annu ar channel for the reception of the upper flange 16 of the "l" 16. These sections 20 and 21 of the clamp are also provided immediately above their grooves 22 with inwardly projecting ribs 23, projecting inwardly beyond the innersurfaces of the sections below the grooves and thus adapted when clamped around the upper end of the l 16, to extend inwardly beyond the inner surface of the T, as shown in Figure 2, to an extent suficient to protect the u per threads16 of the l and form a guidi; for the sucker rod 13 as the latter is lifted out of or inserted into the pump tube 12.

Above each guide rib 23, the sections 20 and 21 of my im roved guide and protector clamp have be've ed portions 24, and these sections at one end are joined by a hinged connection 25 and have vertically spaced exteriorly projecting ears 26 and 27 at their opposite ends.

connecting bolt 28 is pivotally connected,

I as to receive a clamping nut 30 which serves to securely clamp the sections 20 and 21 together and around the upper end of the T 16 in the position shown in Figure 2, it being noted that the lower portion of the clamp section 21 has its lower edge recessed ign order to fit around the side outlet of the It is thus obvious that the clamp provided by my invention 'may be readily connected to and disconnected from the T 16 without requiring removal and reconnection of the polish rod 15 to the sucker rod as is required 1n connection with the ordinary T protecting nipple and it is also obvious that my improved clam will, when in place as shown in Figure 2, e ectively guide the sucker rod durin removal and reinsertion of the latter in or er to protect the upper threads of the T 16.

In removing the sucker rod with my invention in use, the polish rod 15 is after disconnection of the stufiing box 18 from the T 16, raised until the union 14 is substantially above the T 16. My improved clamp is then securely fastened around the upper portion of the T 16 as shown in Figure 2 and then the sucker rod is lifted and disjointed in the usual step by step operation.

I claim:

1. As an article of manufacture, a two part clamp for the upper end of an oil outemma let T, havi means to immovably a; the said out et T and having an internal annular portion adapted to overlie the upper end of the T and to extend inwardly beyond the inner surface of the T in order to protect the latter during withdrawal and reinsertion of a sucker rod through the T. y

2. As an article of manufacture, a sucker rod guide and T protector, consisting of a two-part clamp having means to securely join its parts and having an internal annular groove intermediate its ends and an internal annular rib above said groove.

3. As an article of manufacture, a sucker rod guide and T protector including a twopart clam for engagement with the u per portion 0 an oil outlet T, said clamp aving a hinged connection between its parts at one end and clamping means adapted to connect the parts at their opposite ends, said clamp having an internal annular groove to receive the upper flange of a T and having an internal annular rib above its groove whose inner surface is adaptedto' extend inwardly be ond the inner surface of a T to which t e clamp is applied.

4. As an article of manufacture, a sucker rod guide and T protector including a twopart clamp for engagement with the upper portion of an oil outlet T, said clamp having a hinged connection between its parts at one end and clamping means adapted to onnect the arts at their opposite ends, said clamp groove to receive the upper flange of a T and having an internal annular rib above its groove whose inner surface is adapted to extend inwardly beyond the inner'surface of a T to which the clamp is applied, and said clamp also having an internal tapering surface above the rib as described.
